Attention, Smithsonian magazine readers — and others who like museums! On Saturday a number of area institutions will be open free to holders of Museum Day admission cards (available at the participating institutions, even if you’re not a Smithsonian subscriber). At Betts House, the quirky little museum at 416 Clark St. two blocks west of Music Hall, Julie Carpenter, executive director, says, “Visitors can try their hand at blacksmithing, take a tour or explore our current exhibit. We think it will be fun for kids and grownups.” Among other area participants are the Fire Museum, Xavier University’s Art Gallery, and more museums than you knew existed in Ripley — the John P. Parker House, the Rankin House, a tobacco museum and more. As long as you’re up river, go on to Maysville for the Kentucky Gateway Museum Center.
